Most likely Philips will release an upgrade kit if not only a firmware upgrade in order to enable 3D capabilities on her 8000 and 9000 series, if you have a 200hz and Philips this means you have a 9000 series that could, I'm saying "could" benefit of this (spoken) upgrade...

Debug firmware 3.20 help

Nope you can still install other os in 3.20, maybe your getting confused with the new retail fw 3.21 which releases 1st april which entirely removes other os support. sorry for language english isn't my first.

I can also confirm debug/test 3.20 firmware does have other OS intact unlike retail 3.21 which removes Other OS support. You can upgrade if you have a debug unit. Let's say 3.20 removes other OS, you can always downgrade back to lower firmware up to 2.00 on debug unit. If you want to go lower than 2.00, you need the special 1.50 and 1.00 firmware for debug.
